Tory Mayoral candidate Zac Goldsmith vows tube investment "is safe" in his hands after he made a pledge to reduce overcrowding by investing heavily in transport.
The Richmond Park MP told an audience in Ealing on Monday (February 29) how he plans to support wifi and mobile signal on the key lines.
He also said a major aim is to increase capacity on the Circle, District and Northern lines and was quick to point out Labour rival Sadiq Khan's transport budget plans.
Mr Goldsmith said: "I’ll stand up for London’s commuters by making sure the network gets the investment it needs.
"Khan’s proposals to take £1.9 billion out of the transport budget would not only see London grind to a halt, it would make solving the housing crisis all but impossible.
"This is his flagship policy, and it would devastate Greater London.
"If elected, I will ensure that London has the transport system it needs for the future.”
The mayoral hopeful has also pledged to make sure all new stations are fully accessible to disabled Londoners and deliver a retrofit programme for existing stations to become step-free.
£1.5 million will be invested in the overcrowded lines should he become Mayor, along with signalling upgrades which should increase capacity by 33%.
In his campaign, Mr Goldsmith emphasised that should these plans go ahead, the frequency of the trains will also go up.
Broadband for London plansAs part of his business manifesto, Mr Goldsmith made a promise to business chiefs he will appoint a Digital Chief in City Hall to help tackle some of London's biggest commercial issues.
In his speech, he explained how the vision was to see Transport for London's network of 560km network of railway routes, tunnels and bridges used to rapidly deliver the super-fast broadband London needs.
Research by the Back Zac Campaign said TfL would also benefit from cheap Wi-Fi and a share of the profits as broadband is sold to London’s homes and businesses.
